PLOW.

SPECIEIGATIGN forming part of Letters Patent No. 677,255, dated June'25, 1901. Application filed December 20, 1900. Serial No. 40,547. (Nomodel.)

To all whom it may concern.-

Be it known that 1, ROBERT L. MORRISON, a citizen of the United States,residing at Nathan, in the county of Johnson and State of Texas, haveinventedcertain new and useful Improvements in Plows, of which thefollowing is a specification.

This invention relates to plows,and pertains more particularly toimprovements on my Patent No. 664,570, issued December 25-, 1900.

One object of the present invention is to provide means for slidablyconnecting the moldboard to the plow-standard and for pivot-' allyconnecting the moldboard with a furrowshoe.

A further object of the invention is to provide means for operating theplow-point to make a deep or shallow furrow and for raising and loweringcovering-plows simultaneously with the operation of said opener.

To these ends the invention consists in the novel arrangement andconstruction of parts, and resides, essentially, in the manner ofconnecting the moldboard with the furrow-shoe and the former with theplow-standard.

In the accompanying drawings, forming a part of this application, Figure1 is a longitudinal section. Fig. 2 is a vertical section on the line noFig. 1, looking in the direction indicated by the arrow. Fig. 3 is aperspective view of the levers for operating the moldboard, with thelatter broken away. Fig. 4 is a perspective view of a modification,partly broken away. Fig. 5 is a further modification in longitudinalsection, partly broken away. Fig. 6 is a still further modification inperspective View, partly broken away.

The same numeral-references denote the same parts throughout the severalviews of the drawings.

The plow-beam 1 is of ordinary construction, having a depending standard2, to which is fixed a furrow-shoe 3. The standard 2 has a pin extendingthrough it or is otherwise made with a projection 4 on each side. Themoldboard 5 is provided with a lug 6 and projections 7. The said lug andprojections may be made integral with the moldboard or attached to it inany suitable manner. The

projections 7 have slots 8, fitting the pins 4, to permit theprojections 7 to slide thereon, and the lug 6 is slotted to receive thefront end of the furrow-shoe 3, to which it is hinged or pivoted at 9.Covering-plows 1 have their beams 2 to the projections 7.

To the projections 7 is pivoted a depending lever 10, the other endsthereof being pivoted together and to the short arm 11 of a handlever12, one end 12 of the hand-lever being pivoted to turn in the forwardends of the plow-handles 13 and the other end extending up at the sideof one of the plow-handles, the latter being provided with a rack-bar l4and the former with a plate 15 and a spring 16 to keep the plate in meshwith the rack-bar. It will be seen that by raising the hand-lever theslotted end of the projections 7 will be forced upwardly. This willthrow the point of the moldboard downwardly and the said ends 7 carrythe pivoted ends of the coveringplow beams upwardly, thus lowering thecovering-plows, so that by one movement of the hand-lever all the plowsare given a downward movement, and by a reverse movement of the saidlever all the plows are raised.

Referring to the modification shown in Fig. 4, the moldboard has one arm17 projecting therefrom and integral therewith, which is provided with aslot 18, and the said projection is slidably connected with theplowstandard by a ring or staple 19. The levers 20 for sliding the armor projection 17 are pivoted to the latter forward of the slot 18, and acentral hand-lever 20 is connected to the levers 17 by a yoke-lever 21The moldboard has ears 21 cast or otherwise formed thereon, whicharepivoted to a log 22 on the forward end of the shoe or land-bar 23.This shoe or bar is made in the same piece with the plow-standard andforms the lower terminal of the latter. This form'isshown withoutcovering-plows; but they may be pivoted at the lever pivot-points, ifdesired.

In Fig. 5 is shown a further modification, having the forward portion 24of the landside or shoe-pivoted at 25 to the plow-standard and madeintegral with the moldboard and the rear portion 26 fixed to the saidstandard.

In Fig. 6 is shown a still further modification, the plow-beam having aslot 27, through which works a single arm 28 of the moldboard, thelatter having a depending lug 29, pivoted at 30 in the forked end of theland= side or shoe 31.

It is obvious that in arranging a moldboad to make either of theconnections the devices for accomplishing the same may be bolted,riveted, or otherwise attached to the moldboard, or such devices may becast or welded in place. I therefore do not wish to be .understood aslimiting myself to any particular material or to any special manner ofmaking the connections.

Having thus described my invention, What 1 claim as new, and desire tosecure by Letters Patent, is

- 1. In a plow, the combination, with a furrow-shoe carried by theplow-standard, of a furrow-opener hinged or pivoted to the shoe, themoldboard slidably connected to the standard, and means on the standardto limit the movement of the moldboard.

2. In a plow, the combination of a furrowshoe carried by theplow-standard, a f urrowopener pivoted to the shoe and slidablyconnected to the standard, and the levers for Working the furrow-openeron said pivot.

3. A plow having a hingedor pivoted'moldboard, beams carryingcovering-points and pivoted to the mold'board, and the lovers forsimultaneously working the moldboard and the beams.

4. In a plow, a furrow-opener having a pivot bearing under themoldboard, an arm or projections extending from the moldboard andengaging the plow-standard tolimit the move ment of the moldboard, and afurrow-shoe pivoted to said bearing and fixed to the plowstandard,substantially as set forth.

5. In a plow, the combination of a furrowshoe attached to theplow-standard, a moldboard pivoted to the shoe and having slottedprojections engaging a pin on the standard, covering-plow beams pivotedto said ends, levers depending from said pivot, a lever pivoted to thedepending lever ends, and having a hand-lever for simultaneously workingthe moldboard and the covering-plows on their respective pivots.

In witness whereof I hereunto set my hand in the presence of twowitnesses.

ROBERT L. MORRISON.
